Flow Switches

Flow switches are vital instruments in fluid systems that detect the presence or absence of flow. These devices ensure proper operation and prevent issues such as pump damage or system failure. Flow switches are employed in various industries to monitor and control the flow of liquids or gases, providing a reliable means of safeguarding equipment and optimizing fluid processes.
